摘　　要：结合济钢第二炼钢厂的工艺条件,对留渣操作的热力学和动力学条件进行了分析,探讨了氧气顶吹转炉留渣操作的可行性,指出生产中只要控制炉渣温度低于1508℃就可实施留渣操作;实施留渣操作对转炉冶炼时的初期化渣和脱磷十分有利,并可增加钢水收得率。On the basis of technological conditions of No2 Steelmaking Plant of Jigang, analyzes the condition of thermodynamics and dynamics of remaining slag operation, discusses the feasibility of remaining slag operation on LD converter, points out the remaining slag operation could be actualized on the condition of controlling the slag temperature under 1508℃ At the same time, the remaining slag operation is of benefit to dephosphorization and slagging during the smelting of LD, and it can increase the recycle rate of molten steel
